Unable to reset stroke-dasharray in IE6

[dos1in]

On ie6, setting a path using path.attr({"stroke-dasharray", "- "});
But trying to reset it to be a solid line is impossible. Just like path.attr({"stroke-dasharray", ""});
That's works fine in chrome or firefox.
Finally, setting path.attr({"stroke-dasharray", "none"}); can fix it.

👍 The problem is in the VML module (<= IE8). This line should be changed to:

if ("stroke-dasharray" in params) {
    // ... snipped...
}

So that it sets the empty value if it can't match the dasharray.
